Emulator Issues #9280
Put a message in the TAS system when official DSP files are used.
The TAS Movie code saves a copy of the DSP files inside of the movie file.
I presume this is due to issues arising when recording with official files and playing back with Dolphin's unofficial ones.
Potentially an issue raised when sharing these files to a TAS website for verification purposes and they couldn't verify properly due to DSP files mismatching and causing desyncs? No sure there.
In any case, throw up a message when using the official Nintendo files that distributing the movie file is illegal and you shouldn't do it.
